I recently acquired a #1615 and was comparing the paint job to the one I originally had and noticed that one has an ornamental bell and the other does not. The one without the bell has two indentations above the firebox which I assume was a "placement mark" for the bell. Doyle's book only has one type listed that does not mention the ornament and the picture displays no bell.
I looked on Ebay and saw that most of the ones recently sold were without the bell as only a few had the ornament attached.
Does anyone know if the engine with bell was an earlier/later version, or was included with those sold as a set? Should the engine with the bell be considered "Type 2"? Does this difference make any difference in value?
Thanks,
Greg
